> but I’ve still seen a couple of the MacBook keyboards fail in their short life. One had a key become sticky and unreliable, the other had its space fall off.

The return key on my 2 month old 13" Macbook Pro has already lost its "click". A couple of times a week I have to reboot it to get sound working again. Plugging external monitors in is a coin toss. I have to carry an external dongle around to use it and the dongle gets noticeably warm when in use: what's going on in there?
